Merge tag 'spi-nor/for-5.20' into mtd/next
SPI NOR core changes: - move SECT_4K_PMC flag out of the core as it's a vendor specific flag - s/addr_width/addr_nbytes: address width means the number of IO lines used for the address, whereas in the code it is used as the number of address bytes. - do not change nor->addr_nbytes at SFDP parsing time. At the SFDP parsing time we should not change members of struct spi_nor, but instead fill members of struct spi_nor_flash_parameters which could later on be used by the callers. - track flash's internal address mode so that we can use 4B opcodes together with opcodes that don't have a 4B opcode correspondent.
SPI NOR manufacturer drivers changes: - esmt: Rename "f25l32qa" flash name to "f25l32qa-2s". - micron-st: Skip FSR reading if SPI controller does not support it to allow flashes that support FSR to work even when attached to such SPI controllers. - spansion: Add s25hl-t/s25hs-t IDs and fixups.

Merge tag 'irqchip-5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/core
Pull irqchip/genirq updates from Marc Zyngier:
* Core code update:
- Non-SMP IRQ affinity fixes, allowing UP kernel to behave similarly to SMP ones for the purpose of interrupt affinity
- Let irq_set_chip_handler_name_locked() take a const struct irq_chip *
- Tidy-up the NOMAP irqdomain API variant
- Teach action_show() to use for_each_action_of_desc()
- Make irq_chip_request_resources_parent() allow the parent callback to be optional
- Remove dynamic allocations from populate_parent_alloc_arg()
* New drivers:
- Merge the long awaited IRQ support for the LoongArch architecture, with the provisional ACPICA update (to be reverted once the official support lands)
- New Renesas RZ/G2L IRQC driver, equipped with its companion GPIO driver
* Driver updates
- Optimise the hot path operations for the SiFive PLIC, trading the locking for per-CPU priority masking masking operations which are apparently faster
- Work around broken PLIC implementations that deal pretty badly with edge-triggered interrupts. Flag two implementations as affected.
- Simplify the irq-stm32-exti driver, particularly the table that remaps the interrupts from exti to the GIC, reducing the memory usage
- Convert the ocelot irq_chip to being immutable
- Check ioremap() return value in the MIPS GIC driver
- Move MMP driver init function declarations into the common .h
- The obligatory typo fixes

x86/PCI: Revert "x86/PCI: Clip only host bridge windows for E820 regions"
This reverts commit 4c5e242d3e93.
Prior to 4c5e242d3e93 ("x86/PCI: Clip only host bridge windows for E820 regions"), E820 regions did not affect PCI host bridge windows. We only looked at E820 regions and avoided them when allocating new MMIO space. If firmware PCI bridge window and BAR assignments used E820 regions, we left them alone.
After 4c5e242d3e93, we removed E820 regions from the PCI host bridge windows before looking at BARs, so firmware assignments in E820 regions looked like errors, and we moved things around to fit in the space left (if any) after removing the E820 regions. This unnecessary BAR reassignment broke several machines.
Guilherme reported that Steam Deck fails to boot after 4c5e242d3e93. We clipped the window that contained most 32-bit BARs:
BIOS-e820: [mem 0x00000000a0000000-0x00000000a00fffff] reserved acpi PNP0A08:00: clipped [mem 0x80000000-0xf7ffffff window] to [mem 0xa0100000-0xf7ffffff window] for e820 entry [mem 0xa0000000-0xa00fffff]
which forced us to reassign all those BARs, for example, this NVMe BAR:
pci 0000:00:01.2: PCI bridge to [bus 01] pci 0000:00:01.2: bridge window [mem 0x80600000-0x806fffff] pci 0000:01:00.0: BAR 0: [mem 0x80600000-0x80603fff 64bit] pci 0000:00:01.2: can't claim window [mem 0x80600000-0x806fffff]: no compatible bridge window pci 0000:01:00.0: can't claim BAR 0 [mem 0x80600000-0x80603fff 64bit]: no compatible bridge window
pci 0000:00:01.2: bridge window: assigned [mem 0xa0100000-0xa01fffff] pci 0000:01:00.0: BAR 0: assigned [mem 0xa0100000-0xa0103fff 64bit]
All the reassignments were successful, so the devices should have been functional at the new addresses, but some were not.
Andy reported a similar failure on an Intel MID platform. Benjamin reported a similar failure on a VMWare Fusion VM.
Note: this is not a clean revert; this revert keeps the later change to make the clipping dependent on a new pci_use_e820 bool, moving the checking of this bool to arch_remove_reservations().

x86/PCI: Clip only host bridge windows for E820 regions
ACPI firmware advertises PCI host bridge resources via PNP0A03 _CRS methods. Some BIOSes include non-window address space in _CRS, and if we allocate that non-window space for PCI devices, they don't work.
4dc2287c1805 ("x86: avoid E820 regions when allocating address space") works around this issue by clipping out any regions mentioned in the E820 table in the allocate_resource() path, but the implementation has a couple issues:
- The clipping is done for *all* allocations, not just those for PCI address space, and
- The clipping is done at each allocation instead of being done once when setting up the host bridge windows.
Rework the implementation so we only clip PCI host bridge windows, and we do it once when setting them up.
Example output changes:
BIOS-e820: [mem 0x00000000b0000000-0x00000000c00fffff] reserved + acpi PNP0A08:00: clipped [mem 0xc0000000-0xfebfffff window] to [mem 0xc0100000-0xfebfffff window] for e820 entry [mem 0xb0000000-0xc00fffff] - pci_bus 0000:00: root bus resource [mem 0xc0000000-0xfebfffff window] + pci_bus 0000:00: root bus resource [mem 0xc0100000-0xfebfffff window]
